This build solved two problems for me; first, it allowed me a place to store two bikes when not in use, and second, it allowed me the freedom to roll them around the garage/driveway when cleaning or needing extra room in the garage to work on current projects. Having a single car garage, the need for mobility is of utmost importance. The total cost for this build is under $25, excluding the thrift store office chair.
Step 1: Materials:
(1) Thrift store office chair, the more legs the better.
(1) One 2" piece of PVC approximately 4' in length (height dependent on bikes used)
(1) 2" to 1.5" PVC reducer
(1) 1.5" PVC tee
(1) 1.5" PVC four way piece
(1) 6' piece of 1.5" PVC length
(8) 1.5" PVC 90 degree pieces (possibly more/less depending on design)
(4) 1.5" PVC 45 degree pieces (possibly more/less depending on design)
(4) 1.5" PVC caps (purely for aesthetics)
Step 2: Liberating the base
Remove office chair base: typically, the chair will have a pin or clip holding the chair strut to the rolling base. Remove said pin and free chair from legs. You now have a really cool rolling base and a completely useless chair. Donate the remaining chair carcass to someone who only has a really cool rolling base and is need of something to put on top of it, or just toss it out.
